Work of the sand dredger is mainly to sieve particle via a sieve and get expected sieving product to improve efficiency of the sand dredger. Just as its name implies a good sieve shall be selected to improve the sieving efficiency. What kind of sieve shall be selected to improve efficiency of the dredger? Some suggestion is shared below. 
First, sieve with large sieve pore can be selected during purchasing, which can increase vibration force and adhesive force of material. Larger sieve pore can make the material sieved rapidly and reduce clogging to improve sieving efficiency. Users can also adopt multilayer sieve that realize the purpose of rapid sieving and overcoming clogging through sieving different particles to different panels. Improving efficiency of the sand dredger has significant impact on current sand mining industry and increases benefit of the sand mining industry greatly.
